Abstract
An object of the present disclosure is to implement a coloring pattern with a high optical density on an electrode substrate to improve display reliability and lifetime of a display as well as vivid colors. That is, the present disclosure relates to a composition and a method that can form the pattern of a pixel defining layer that can improve visibility and contrast by satisfying the optical density of 0.80/μm to 1.5/μm in the panel after post-baking treatment.
